To all whom it may concern: y

Be it known that I, WILLARD F. RICHARDS, a citizen of the United States,residing at the city of Buffalo, in the county of Erie and State Y ofNew York, have invented a new and useful applicable to low Hat cars inwhich it is de-A sirable to operate the locking pawl from the under sideof the drawhead. e

My invention has for lits object to simplify the devices foroperatingvthe locking pawl, and to construct the same in such a mannerthat the upper incline, with which the draw-y yhead is commonly providedfor swinging the lock backward, may be dispensed with.

In the accompanying drawings: Figure 1 is a longitudinal sectionalelevation of my improved coupling, showing the coupling jaw in itsclosed or coupled position. Fig. 2 is a cross section thereof in line2-.2, Fig. l, showing the parts in the same position. Fig. 3 is ahorizontal section of the coupling in its locked position. Fig. 4isasideelevation of the drawhead, showing the chain for operating the rockshaft ofv the lock-shifting lever. Fig. 5 is a longitudinal sectionalelevation corresponding to Fig. 1, showing the lock swung back out ofenga-gement with the arm of the coupling jaw and raised on its incline.

Like letters Of reference refer to like parts in the several figures.

A is the drawhead, having the usual chamber for receiving the movableparts of the coupling.

B is the coupling jaw or knuckle pivoted to the drawhead by an uprightpin b, in the ordinary manner, and having the usual locking arm b.

. Gis the lock or pawl which engages withA the arm of the coupling jawfor locking the jaw in Yits coupled position, and which swingshorizontally on an ,upright pin c that is free to rise and fall in itsopenings in the drawhead, so as permit the lock to move vertically aswell as swing horizontally.

CZ is the usual rearwardly-rising incline arl ranged on the drawheadunderneath the lock,

for automatically moving the latter forwardly into engagement with thearm of the coupling jaw when the jaw is swung intoits closed position. Y

Eis a horizontal rock shaft arranged transversely on the under side ofthe drawhead and journaled in perforated lugs or bearings e formed onthe adjacent portion'of the drawhead.

e is a shifting arm or lever mounted on the.

rock shaft and adapted to move the lock back- 1 4ward out of engagementwith the coupling jaw andat the same timelift it on its incline. Thisshifting lever swings upward and backward in a vertical plane andextends forwardly and upwardly from the rock shaft, through alongitudinal slot fforrned in the lower wall of the drawhead. Theshifting lever is adapted to engage with its free end against a shoulderg formed on the adjacent under side of the swinging lock (l, as shown inFigs. l and 5, the lever being preferably provided at its free end witha lip or shoulder e2 which bears against the shoulder ot' thelock. Theshoulder of the lock is produced by forming a longitudinal recess g inthe lock, which recess extends to the front edge of the lock.

h is an actuating lever or arm secured to the Outer end of the rockshaft for turning the same, and t' is an Operating chain attached at itslower end to said arm and at its upper end to the arm of the usualuncoupling shaft journaled on the end sill of the car.

In the locked position of the coupling jaw,

the'lock is engaged With the arm of the jaw and the shifting leverestands with its free end in close proximity to the shoulder on` theYunder side of the lock, as shown in Figs. l and 2. When it is desiredto unlock the coupling jaw for uncoupling the cars, the chain z' ispullednpward, which eausestherockshaft to be turned inthproper directionitoswing the shifting lever upward and backward to the position shown inFig. 5. This movement of the shifting lever is imparted to the lock bythe free `end of the lever bearingagainst the shoulder of the lock,causing the lock "to be moved backward out of engagement with the armofthe coupling jaw and at the same time elevated on its incline. Thecoupling jaw, being now released, is free to swing to its open position.Upon releasing the chain, the shifting lever drops to itsformer'positionfand the; lock descends on its incline. When the coup-Lling jaw is swung inward to "its locked posi-` tion by contact withthecoupling of an opposin'gqcar, its farm; strik-ing the ilokyswings thellatter backward on `its incline and'assoo'n aslthflki-giann*passfsmwaraiiyonatheir@ exija` ofn the-lock, :ne Latterridsvdow'n its 111-' eline 'and automatically interlocks with fthearino'f the couplingfjawinthe lnsualinaimer.
